The Jacksonville-based truckload carrier's transition to LNG was driven by three factors: addressing customers’ sustainability goals, contributing to U.S. energy independence, and lowering fuel costs for the 500-truck fleet.

The temporary highway funding bill passed this summer changed how liquified natural gas is taxed to make it more equitable to diesel fuel, and one LNG provider believes that will lead more fleets to consider using it as an alternative fuel.

At a time when many shippers have chief sustainability officers and government contracts are requiring low-emissions or alternative-fuel equipment, some fleets are finding it pays to have natural gas trucks in their arsenal.
